Abstract: The present invention relates to a lighting device comprising a main body (10), a lighting body (20) and an anodized metal filter (30), in which said metal comprises a superficial porous layer of an oxide of said metal comprising at least one antimicrobial substance. In one embodiment, the filter comprises a plurality of threadlike elements of said anodized metal, at least partially in non-permanent contact with each other, randomly deformed to form a plurality of non-linear pathways. The air to be treated passes through said filter owing to the effect of a difference in temperature and/or the action of a mechanical device. In other embodiments, the filter comprises a metal sheet with holes.

Abstract: A device which can be fixed to the edge of a panel, for example a sound-absorbing panel formed by heat-bonded synthetic fibers, is disclosed. The device includes a body with a longitudinal through-hole and two walls which define a cavity for enclosing the edge of the panel. The through-hole communicates with the cavity. The through-hole is configured to guide a threaded element (screw or the like) towards the cavity so that the threaded element engages at least with the edge of the panel so that it expands towards the walls of the cavity and is firmly retained by them.

Abstract: A joining element for connecting together two or more panels is disclosed. The joining element includes at least one strip section; wherein the strip section forms a first part and a second part; wherein the first part and the second part are connected together along a hinge line or area. In addition, the second part includes a connection member designed to engage with a complementary connection member. In one embodiment the connection members comprise a button and an eyelet.
